Who pays for shipping cost?
Shipping costs are calculated by the supplier upon receipt of the order. They are borne by the reseller.
The reseller pays the supplier's price for the product and the delivery costs to the end customer.
The customer pays the selling price of the product and the delivery costs defined by the reseller on his website.
Shipping costs are not imported, as they vary according to different parameters. However, you can define specific delivery profiles on your site.
